Description

Technical Field

[0001] The utility model relates to the technical field of making soup with old hens, and specifically relates to a lifting crane. Background Technique

[0002] A crane is the common name for a hoist, a bridge crane, a overhead crane, etc. A crane is basically the same as what we call a hoist. There are basically two types of driving methods for a crane: one is centralized drive, that is, one motor drives the long drive shaft to drive the driving wheels on both sides; the other is separate drive, that is, each of the driving wheels on both sides is driven by one motor. Medium and small bridge cranes mostly adopt the "three-in-one" drive method in which a brake, a reducer and a motor are combined into one. For ordinary bridge cranes with large lifting weights, in order to facilitate installation and adjustment, a universal coupling is often used for the drive device. A mother hen soup is the soup made with old hens. In industrial production, a crane is required for assistance to make a large amount of mother hen soup;

[0003] Some existing lifting cranes adopt the method of fixing the height position of the working arm to realize the lifting work of the materials for making mother hen soup;

[0004] There are some problems now. Adopting the method of fixing the height position of the working arm may limit the applicable working range of the lifting crane, and thus may affect the working efficiency of the lifting crane. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to overcome the existing defects, and provide a lifting crane that can realize the height adjustment of the working arm, effectively meet the requirements of different working environments, and thus effectively improve the auxiliary efficiency of making mother hen soup, and can effectively solve the problems in the background technique.

[0006] To achieve the above object, the utility model provides the following technical solution: A lifting crane, including a support plate and a lifting mechanism;

The upper end of the lifting plate is fixedly connected with a support pipe. The upper end of the support pipe is fixedly connected with a connection disk. The upper end of the connection disk is rotatably connected with a rotating disk. The upper end of the rotating disk is fixedly connected with a connection column. The upper end of the connection column is fixedly connected with a working arm. Slide rails are arranged at both the front and rear ends of the working arm. Rollers are slidably connected inside the slide rails. A sliding frame is arranged between the rotating shafts of the rollers. The lower end of the sliding frame is rotatably connected with a winch. A cable is wound around the outer surface of the winch. The lower end of the cable is fixedly connected with a hook;

[0008] Lifting mechanism: It is arranged between the support plate and the lifting plate, can realize the height adjustment of the working arm, effectively meet the requirements of different working environments, and thus effectively improve the auxiliary efficiency of making mother hen soup.

[0009] Further, a control switch group is arranged at the left end of the upper surface of the support plate. The input end of the control switch group is electrically connected to an external power supply to control the operation of the motor.

[0010] Further, the lifting mechanism includes an adjusting seat, a first connecting rod, a first U-shaped seat, a second connecting rod and a second U-shaped seat. The first U-shaped seat is fixedly connected to the center of the upper surface of the support plate. The first connecting rods are symmetrically and rotatably connected to the upper ends of the first U-shaped seat. The upper ends of the first connecting rods are all rotatably connected with the adjusting seats. The second connecting rods are respectively rotatably connected to the upper ends of the adjusting seats. The second U-shaped seat is fixedly connected to the center of the lower surface of the lifting plate. The upper ends of the second connecting rods are all rotatably connected to the lower ends of the second U-shaped seat, so as to realize the lifting of the lifting plate, and further realize the lifting of the working arm.

[0011] Further, the lifting mechanism further includes a driving disk and a bidirectional lead screw. The bidirectional lead screw is threadedly connected between the two adjusting seats. The driving disk is fixedly connected to the front end of the bidirectional lead screw to provide driving force for the lifting of the working arm.

[0012] Further, a first motor is arranged at the right end of the front side surface of the sliding frame. The output shaft of the first motor is fixedly connected to the longitudinally adjacent rotating shaft. A second motor is arranged at the lower end of the right side surface of the sliding frame. The output shaft of the second motor is fixedly connected to the right end of the winch. The input ends of the first motor and the second motor are both electrically connected to the output end of the control switch group to provide driving force for the lateral movement of the sliding frame and the vertical movement of the hook.

The input end of the third motor is electrically connected to the output end of the control switch group to realize the rotation of the working arm.

[0014] Further, uniformly distributed moving seats are fixedly connected to the lower end of the support plate. Moving wheels are arranged at the lower ends of the moving seats to facilitate the movement of the lifting hoist.

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows: This lifting hoist has the following advantages:

[0016] When a person rotates the driving disk, the driving disk rotates to drive the bidirectional lead screw to rotate.

The opposite movement of the connecting seats all drives the upper ends of the vertically adjacent first connecting rods and the lower ends of the second connecting rods to move towards the direction close to the center of the support plate. Furthermore, the upper ends of the second connecting rods push the lifting plate through the same second U-shaped seat, so that the lifting plate moves upward under the guiding action of the guiding columns. The upward movement of the lifting plate drives the support pipe to move upward, and further drives the working arm to move upward through the connecting column, which can realize the height adjustment of the working arm, effectively meet the requirements of different working environments, and further effectively improve the auxiliary efficiency of the old hen soup-making work.

A working arm 6 is fixedly connected to the upper end of the connecting column 5. Slide rails 9 are arranged at both the front and rear ends of the working arm 6. Rollers 11 are slidably connected inside the slide rails 9. A sliding frame 10 is arranged between the rotating shafts of the rollers 11. A winch 13 is rotatably connected to the lower end of the sliding frame 10. A cable is wound around the outer surface of the winch 13. A hook 15 is fixedly connected to the lower end of the cable. A control switch group 17 is arranged at the left end of the upper surface of the support plate 1. The input end of the control switch group 17 is electrically connected to an external power source. Uniformly distributed moving seats are fixedly connected to the lower end of the support plate 1. Moving wheels 18 are arranged at the lower ends of the moving seats;

[0025] Lifting mechanism 3: It is arranged between the support plate 1 and the lifting plate 2. The lifting mechanism 3 includes an adjusting seat 33, a first connecting rod 34, a first U-shaped seat 35, a second connecting rod 36 and a second U-shaped seat 37. The first U-shaped seat 35 is fixedly connected to the center of the upper surface of the support plate 1. The first connecting rods 34 are symmetrically and rotatably connected to the upper ends of the first U-shaped seat 35. Adjusting seats 33 are rotatably connected to the upper ends of the first connecting rods 34. The second connecting rods 36 are respectively rotatably connected to the upper ends of the adjusting seats 33. The second U-shaped seat 37 is fixedly connected to the center of the lower surface of the lifting plate 2. The upper ends of the second connecting rods 36 are respectively rotatably connected to the lower ends of the second U-shaped seat 37. The lifting mechanism 3 further includes a driving disk 31 and a bidirectional lead screw 32. The bidirectional lead screw 32 is threadedly connected between the two adjusting seats 33. The driving disk 31 is fixedly connected to the front end of the bidirectional lead screw 32. By rotating the driving disk 31, the driving disk 31 rotates to drive the bidirectional lead screw 32 to rotate. The rotation of the bidirectional lead screw 32 causes the connecting seats 33 to move towards the center of the support plate 1. The opposite movement of the connecting seats 33 drives the upper ends of the vertically adjacent first connecting rods 34 and the lower ends of the second connecting rods 36 to move towards the center of the support plate 1. Furthermore, the upper ends of the second connecting rods 36 push the lifting plate 2 through the same second U-shaped seat 37, causing the lifting plate 2 to move upward under the guiding action of the guiding columns 19. The upward movement of the lifting plate 2 drives the support tube 4 to move upward, and then drives the working arm 6 to move upward through the connecting column 5;

[0026] Among them: A first motor 12 is arranged at the right end of the front side surface of the sliding frame 10. The output shaft of the first motor 12 is fixedly connected to the longitudinally adjacent rotating shaft. A second motor 14 is arranged at the lower end of the right side surface of the sliding frame 10. The output shaft of the second motor 14 is fixedly connected to the right end of the winch 13. The input ends of the first motor 12 and the second motor 14 are electrically connected to the output end of the control switch group 17. When the first motor 12 operates, the output shaft of the first motor 12 rotates to drive the longitudinally adjacent rotating shaft to rotate. The rotation of the rotating shaft drives the corresponding roller 8 to rotate. The roller 8 slides inside the corresponding slide rail 9, thereby realizing the lateral movement of the sliding frame 10. The movement of the sliding frame 10 drives the winch 13 to move laterally. When the second motor 14 operates, the output shaft of the second motor 14 rotates to drive the winch 13 to rotate, thereby realizing the release of the cable, and then realizing the downward movement of the hook 15. When the hook 15 moves downward to the required position, the materials required for stewing the old hen are hooked. Then, by operating the control switch group 17, the second motor 14 rotates in the reverse direction to realize the lifting of the materials;

[0027] Among them: A third motor 16 is arranged on the top wall of the support tube 4. The output shaft of the third motor 16 is fixedly connected to the lower end of the rotating disk 8. The input end of the third motor 16 is electrically connected to the output end of the control switch group 17. When the third motor 16 operates, the output shaft of the third motor 16 rotates to drive the rotating disk 8 to rotate. The rotation of the rotating disk 8 drives the connecting column 5 to rotate, thereby realizing the rotation of the working arm 6. The rotation of the working arm 6 drives the materials to rotate.

[0028] The working principle of a lifting hoist provided by the utility model is as follows: During operation, a person pushes the support pipe 4, causing the moving wheels 18 to rotate, thereby realizing the movement of the lifting hoist. When the lifting hoist moves to the required working position, the person stops pushing the support pipe 4. Then, the person rotates the driving disk 31. The rotation of the driving disk 31 drives the rotation of the bidirectional lead screw 32. The rotation of the bidirectional lead screw 32 causes the connecting seats 33 to move towards the center of the support plate 1. The opposite movement of the connecting seats 33 drives the upper ends of the first connecting rods 34 and the lower ends of the second connecting rods 36 adjacent vertically to move towards the center of the support plate 1. As a result, the upper end of the second connecting rod 36 pushes the lifting plate 2 through the same U-shaped seat two 37, causing the lifting plate 2 to move upward under the guiding action of the guiding column 19. The upward movement of the lifting plate 2 drives the upward movement of the support pipe 4, and then drives the working arm 6 to move upward through the connecting column 5. When the working arm 6 moves to the required height, the person stops rotating the driving disk 31. Then, the person realizes the operation of the first motor 12 through the control switch group 17. The output shaft of the first motor 12 rotates to drive the rotation of the longitudinally adjacent rotating shafts. The rotation of the rotating shafts drives the corresponding rollers 8 to rotate. The rollers 8 slide inside the corresponding slide rails 9, thereby realizing the lateral movement of the sliding frame 10. The movement of the sliding frame 10 drives the lateral movement of the winch 13. When the winch 13 moves to the required position, the person turns off the first motor 12 through the control switch group 17 and realizes the operation of the second motor 14. The output shaft of the second motor 14 rotates to drive the rotation of the winch 13, thereby realizing the release of the cable, and then realizing the downward movement of the hook 15. When the hook 15 moves downward to the required position, the materials required for stewing the old hen are hooked. Then, the person realizes the reverse operation of the second motor 14 through the control switch group 17 to realize the lifting of the materials. When the materials reach the specified height, the person turns off the second motor 14 through the control switch group 17 and realizes the operation of the third motor 16. The output shaft of the third motor 16 rotates to drive the rotation of the rotating disk 8. The rotation of the rotating disk 8 drives the rotation of the connecting column 5, thereby realizing the rotation of the working arm 6. The rotation of the working arm 6 drives the rotation of the materials. When the materials rotate to the required position, the third motor 16 is turned off through the control switch group 17. Then, the second motor 14 is operated to release the cable, thereby realizing the release of the materials, and then completing the auxiliary work of the old hen stewing work.

[0029] It should be noted that in the above embodiments, the first motor 12 disclosed can be a 5IK120A - AF motor, the second motor 14 can be a ZDY131 - 4 - 4.5KW hoisting motor, the third motor 16 can be an MHMF082L1U2M servo motor, and the control switch group 17 is provided with control buttons corresponding to the first motor 12, the second motor 14, and the third motor 16 one by one to control their switches.

[0030] The above are only embodiments of the present utility model, and do not thus limit the patent scope of the present utility model. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall similarly be included within the patent protection scope of the present utility model.
